KJV:
Therefore I hated life; because the work that is wrought under the sun is grievous unto me: for all is vanity and vexation of spirit.
NASB:
So I hated life, for the work which had been done under the sun was grievous to me; because everything is futility and striving after wind.
KJV:
Yea, I hated all my labour which I had taken under the sun: because I should leave it unto the man that shall be after me.
NASB:
Thus I hated all the fruit of my labor for which I had labored under the sun, for I must leave it to the man who will come after me.
KJV:
And who knoweth whether he shall be a wise man or a fool? yet shall he have rule over all my labour wherein I have laboured, and wherein I have shewed myself wise under the sun. This is also vanity.
NASB:
And who knows whether he will be a wise man or a fool? Yet he will have control over all the fruit of my labor for which I have labored by acting wisely under the sun. This too is vanity.
KJV:
Therefore I went about to cause my heart to despair of all the labour which I took under the sun.
NASB:
Therefore I completely despaired of all the fruit of my labor for which I had labored under the sun.
KJV:
For there is a man whose labour is in wisdom, and in knowledge, and in equity; yet to a man that hath not laboured therein shall he leave it for his portion. This also is vanity and a great evil.
NASB:
When there is a man who has labored with wisdom, knowledge and skill, then he gives his legacy to one who has not labored with them. This too is vanity and a great evil.
KJV:
For what hath man of all his labour, and of the vexation of his heart, wherein he hath laboured under the sun?
NASB:
For what does a man get in all his labor and in his striving with which he labors under the sun?
KJV:
For God giveth to a man that is good in his sight wisdom, and knowledge, and joy: but to the sinner he giveth travail, to gather and to heap up, that he may give to him that is good before God. This also is vanity and vexation of spirit.
NASB:
For to a person who is good in His sight He has given wisdom and knowledge and joy, while to the sinner He has given the task of gathering and collecting so that he may give to one who is good in God's sight. This too is vanity and striving after wind.
